P13 not working

just got my BOE-BOT kit today.
completed chapters 1&2 up to/through the servo timing exercises.
took a break before the actual building section.
came back to show the kids the servos turning etc.
only p12 is turning. odd.
so I try just the LEDs. only p12 lights,
so I switch the servo and LED to p14 and rewrite the code and it works perfectly.
go back to p13 and nothing.
odd thing is if I gently bump/hold the resistor on p13 the servo goes into continuous mode. I do not get the same result with p12.
again putting servo /resistor in p14 works
in P13 doesn't work. previosly worked. using 4 AA 1.5v batteries for power and the jumper is in the correct spot.
BOE serial with USB adapter REV C
I also tried it w/o being connected to PC no different,
power was off and USB was disconnected during the time when it worked and when it quit.
Ideas?

I powered everything down
